Question

The rate constant for a gaseous reaction,
X(g) + 2Y(g) is 0.2 mol L-1 s-1. If initial
concentration of the reactant, X is 0.8 mol L-1,
which of the following graph is correct?​

Answer 1

Answer:

0.72M

Explanation:

The rate constant has unit mole per second which indicates zero order reaction.

x = kt

The concentration of B after 20 minutes is 20×60×0.6×10

−3

=0.72M
